Working Principles

The MC74VHCT259ADT operates by using the control signals (S0-S3) to select one of the eight data inputs (A0-A7) and route it to the output pins (Q0-Q7). The OE (Output Enable) pin controls the output state. When OE is low, the selected data input appears at the outputs. When OE is high, the outputs are in a high-impedance state.

Detailed Application Field Plans

The MC74VHCT259ADT can be used in various applications, including:

1. Data multiplexing in microcontrollers and digital signal processors.
2. Address decoding in memory systems.
3. Input selection in audio/video equipment.
4. Channel selection in communication systems.
5. Control signal routing in industrial automation.
